About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-30S
The AirTAC SAIJ200X350-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 320 to 350 mm, allowing you to dial back the nominal 350 mm stroke by up to 30 mm during commissioning without swapping the unit.
This variant includes a standard carbon steel rod and a magnet for position sensing. It features PT tapered port threads and dual-side sensor grooves compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The extruded aluminum barrel design integrates adjustable air cushions at both ends to decelerate the massive 40 mm rod smoothly.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-30S Is Used
Heavy Press Tuning
Fine-tune the exact bottom-out position of a heavy press during setup, trimming the stroke by up to 30 mm to accommodate varying material thicknesses without external stops.
Pallet Changeover
Adjust the retract end-stop on the fly when switching a conveyor line to handle different pallet lengths, ensuring precise positioning without changing the cylinder.
Large Assembly End-Stop
Dial in the exact end-position for a massive assembly fixture, using the rear screw to set the 320-350 mm travel window perfectly during initial machine commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-30S the Right Cylinder?
The adjustable rear stopper is chosen over a fixed-stroke SAI cylinder when you need variable end-stops for product size changeovers on a line. It uses PT tapered port threads and operates at speeds of 30-500 mm/s.
Because the 350 mm stroke is substantial, the 40 mm rod and M36x2 thread provide rigidity, but an external guide is still recommended to prevent excessive side-loading on the piston. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-30S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear external screw acts as a mechanical stop that allows you to shorten the effective travel from the nominal 350 mm down to 320 mm. This adjuster and the air cushions only decelerate the end of travel; they do not lock or hold the load without continuous air pressure.
